    Hi I have a 2020 denali 3l with arc .I ordered the upper 2 in mounts with the arc brackets. I could not find 1 in blocks so I ordered a front and rear kit without arc from ebay .going to use rear blocks and sell the front 2 in upper spacers .

    Just picked up new truck today denali 3l .wanting a 2 or 2.5 in lift or level .are the 2.5 in harder on the cv joints .I know if I go 2.5 in front I have to go with 1.5 in blocks in rear .are the rough country style not as good as the upper strut mount style as the lower can tear boots from the bolts .sorry for all the questions want it write the first time
  15. cbprov
